UNITED STATES FREDERICK vW. SCHEIFELE, 0F AUDUBON, 'NEW JERSEY.

61L BURNER.

Application filed September 15, 1923. Serial No. 662,864.

T 0 all whom it may concern: Be it known that I, FREDERICK SOHEIFELE, a citizen of the United States,

residin at Audubon, in the county of Cam'- den an State of New Jersey, have invented certain new and useful Improvements in, Oil Burners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in oil burners and it is an object of the invention to provide a device of this general character particularly designed and adapted for use in connection with furnaces and more particularly of a hot water, hot air or steam type.

Another object of the invention is to pro vide a novel and improved .deviceof this general character wherein the fuel is vaporized by the flame of the burner.

The invention consists in the details of construction and in the combination and arrangement of the several parts of myimproved oil burner whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and'advantageous for use, as will he hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is an elevational view illustrating a burner constructed in accordance with an embodiment of my invention and in applied position, an associated furnace being indicated by broken lines;

Figure 2 is a sectional view taken substantially on the line 22 of Figure 1, looking in the direction of the arrows, a portion of the associated furnace being also indicated by broken lines;

Figure 3 is an enlarged fragmentary sectional view taken substantially on the line 3-3 of Figure 2;

Figure 4 is a fragmentary view partly in section and partly in elevation illustrating the means as herein disclosed for automatically cutting off the supply of fuel,

As disclosed in the accompanying drawings, '1 denotes a-supply tank of desired capacity and which has leading therefrom a feed pipe 1, said pipe being provided with an extension 2 preferably disposed across and adjacent to the entrance to the ash pit of the furnace and which serves as a manifold. 1 1

In the assembly as disclosed in the. accompanying drawings, I provide an equipment wherein two burners areemployed and each of said burners comprises a pan 3 provided at its central portion with a, continuous flange 4 to provide a cup within the pan 3.

The pan 3 adjacent a marginal portion thereof is provided therethrough with a stepped opening 5 and in the lower orenlarged portion of said opening is threaded or otherwise connected an end portion of a pipe 6, said pipebeing of a length to extend within the ash .pit and has its lower end portion connected by the pipe 7 with an upstanding return pipe 8 in communication with the extension or manifold 2. Interposed in the return pipe 8 is a controlling valve 9.

Positioned a desired distance above each of the pans 3 and particularly above a cup 4 is a hollow member 10 herein disclosed as substantially conical in form, and said member 10 is supported in desired position by the pipe 11. This pipe 11 is secured to and in communication with the interior-ofthe member 10 and also engaged within the upper or smaller portion of the opening 5 of the pan 3 and is disposed on such curvature to assure the desired maintenance of the member 10 in applied position.

Secured to the upper or apex portion of the member 10 and in communication with the interior thereof-is a coupling '12 with which is engaged a pipe 14, said pipe being disposed in a manner to extend downwardly to a point below the member 10 and terminating in an extension or portion 15 arranged directlybelow the member 10. Securedto the lower or free end portion of the pipe 14 is a burner 16, the flame opening 17 of which being, disposedtoward the member 10.

In practice, when it is desired to usea burner, alcohol or kindred fuel is ignited within the cup 4 resulting in heating the member 10 to a relatively high degree. After the member 10 has been heated the valve 9 is opened to permit the fuel, such as kerosene or the like, to fl'ojwthrough the pipe 6 and through the pipe 11 into the heated;

member 10 where said fuel is gasified, and as the gas expands it goes to the upper or apex portion of the member 10. The memthat when it emerges at the ignition open-K ing 17, the flow is steady assuring an even flame at all times. New gas is formed just as soon as the oil from the pipe 11 strikes the bottom of the member 10 and such gas forces the previously heated gas out through i the member 10 and pipe 14, thus preventing carbonization in the member 10. The speed at which the gas is forced out of the member 10 prevents said gas from burning and "carbonizing in said member; Theflame of the burner 16 in addition to producing the requisite heat for the furnace or the like also serves to maintain the memberlO at desired temperature to'assure the gasifying' of the low grade fuel.

Interposed in each of the pipes 7 is a check Valve 18 which'closes in the event of back pressure whereby the efiicacy of the burner is materially increased, because the burner 16 is prevented from carbonizing at the opening 17, for, when the opening-17 receivesa carbon deposit causing such opening to be reduced, the pressure becomes greater and being held by the check valve 18 causes the carbon deposit to be blown out of the opening 17.

Each of the pans 3 has in communication therewith, as at 19 from below, a discharge pipe 20. Common to both of 'the pipes 20 is a carry off pipe 21 which is adapted to discharge within a bucket B.

The bucket B as herein disclosed is suspended from an operating stem 22 associated with a controlling valve 23 interposed in the extension or manifold 2 at a point in advance of both of the pipes 8. The pipe 1' at a predetermined point above the extension or maniold 2' has secured thereto an outstanding bracket 24. Connected to the bracket 24 is an extremity of a retractible spring 25 the opposite extremity of said spring being also secured to the valve stem 22. The spring 25 is of sufficient tensionto' maintain the valve 23 normally in open position. In the event; the flame of a burner 16 should go out, the oil'which will continue to flow "out of the opening 1'7 will pass through the pipes 20 and21 and into the bucket B, the weight of the oil collected within said bucket 'B will swing the'stem 22' downwardly or in a direction to close the valve 23.

' reason of the convenience and facility with which it may be assembled and operated, and it will-also be obvious that my, invention is'susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. An oil burner comprising a pan, a hollow member positioned above the pan, said member being conical in form with its apex upwardly disposed, a pipe connected to the pan and member and in communication with the lower portion of the member, said pipe maintaining the member in applied position with respect to the pan, said pipe being adapted forcommunic'ation with a source of fuel supply, a second pipe leading from the apex of the member and in communication therewith and having its free end portion terminating between the member and pan,

member in applied position with respect to the pan,said p pe being adapted for communication with a source of fuel supply, a second pipe leading from the apex of said member and in communication therewith and having its free end portion terminating between the member and pan, a burner carried by said free end portion of the last named pipe, and an overflow, pipe in communication with the pan. v I

3. An oil burner comprising a pan, a hollow member positioned above the pan, said member being conical in form with its apex upwardly disposed, a pipe connected to the pan and member and incommunication with the member, said pipe maintaining the member in applied position with respect to the pan, a feed line in communication with said pipe, a valve interposed in said feed line and closing upon back pressure, said pipe being adapted for communication with a. source of fuel supply; a secondpipe leading from the apex of said memberand in communication therewith and having its free end portion terminating between the member and pan, and a burner carried by said free end portion of the last named pipe.

In testimony whereof I hereunto atiix my signature. V
